SUSPENDED ARCH Eon BoILEnS AND THE LIKE.

To all whom z't may concern:

Be it known that I, lVAL'rER E, GEHRING, a citizen of the United States, and resident of Milwaukee in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Suspended Arches for Boilers and the. like; and.

I do hereby declare that the following is a full, clear, and exact description thereof.

My invention pertains to improvements in the means for mounting the liningsof furnaces, kilnsqand the like, and refers particularly to means for suspending the arches of such types of apparatus.

The arches and other parts of lining of furnaces and thelike are ordinarily constructed of a plurality of fire bricks, and un der modern practice it is customary to mount or suspend the same in spaced relation to the mainsupporting means in order to prevent the latter from being readily burnt out. When arches are so supported, a considerable number of the lining bricks are suspended from a single hanger so that when it is necessary to replace a single one of the bricks, all of the others on this particular hanger'must be removed; As many of the bricks removed are rendered useless, the replacement of the single defective brick is an expensive procedure. The same is true when the hanger on which a plurality of bricks is suspended isburnt out, or needs ire lacing for any other reason.

t is therefore the principal object of this invention to provide means whereby the; several lining or arch bricks may be individually suspended. This obviously permits the removal of a single brick "without interfering with any eof the other bricks comprising the lining or arch.

With these general objects in view, the invention consists in the novel features of con struction, combination and arrangement of parts hereinafter described and claimed and which are shown in the accompanying drawing, wherein:

Figure 1 represents an'elevational view of a supporting means for a lu'rality of arch brlcks, each of which is individually suspended. n

through the main supporting means, the arch bricks and their hangers-being in elevation. r

Fig. 3 is a lowerjplan view of the abutting ends of two elements of the main support- Specification of Letters Patent. Patented an, 20, 1920, application filed May 12, 1919. Serial No. 296,446.

ing frame, a pair of hanger bars to be associated therewith being in transverse sec tion, and I p Fig. 4; is a detail elevational view of the parts shown in Fig. 3.

Inasmuch as my invention is capable of useinmany types of furnaces, kilns and analogous apparatus, the use of the same in any particular application has not been illustrated in the accompanying drawings.

, It is also to be understood that various changes may be made in the form and pro portion of the several parts of the invention and in the manner of using the same, without departing from the principles thereof .as outlined in the succeeding description faces opposed and secured in spaced rela-- tion by transverse spacing bolts 2. At a plurality of points on the bars 1 are located upper transverse tie plates 3 which carry tie rods 4 by which the frames A are secured. to said beams B.'

,' a Each of thesupporting frames A consists.

ofa plurality of sections, one of which is located between each adjatent pair of beams B as'mpst clearly shown in Fig. 1. Each of the several frame sections is shown in the accompanying drawings. as having its sev-.

eral parts cast integrally, said parts includmg an elongated horizontal plate 5, a vertical reinforcing rib 6, and a pair of dependng angle bars 7 which extend parallel to each other throughout the length of the plate 5 and'have their like faces opposed, thus forming an elon ated chamber running from one end o the section to the other. The angle bars 7 have their adjacent horizont'aLfia-nges spaced apart to provide an elongated passageway into said chamber.

The ends of the several sections of the frames 'A are secured to the under sides of the beams B'by means of said tie rods 4; and lower tie plates 8 which extend through slots 9 in the bars? as shown in Fig. 4. Lugs 10 on theplates 5 engage the opposite sides or, transverse beams B,

' 30 tangul'ar, or substantiall of thelower tieplates 8 to aid in construct- 1 ing a'rigid joint between the several frame sections and the adjacent beams. The 'sev-' eral frame sections being alined, the cham- 5 bers resulting from the spacing of the angle bar 7 are likewise alined and extend from one end to the other of each of the frames A.

- The fire bricks which form the' arch. or boiler lining are adapted to be' spaced from 10 the frames A and individually suspended therefrom by a plurality of hanger bars 11. Each of the hanger bars lllhas a T-head 12' of a widthless than the distance between the horizontal fl'angesof the angle bars 7 and 15 of a length which is greater "than said distance.- Thus said heads may be readily disposed. within the chamber defined by said angle bars 7 by first alining the same with the angle bars and then'rotating the hanger bars 11 to, dispose said heads transversely.

These two positions of the heads are indi-,

used in an. arch the openings 16 are at the Y It'iops thereof, and the other portions of the slots 15 are substantially horizontal; .The ends of the hanger Y gage. in said slots- 15 are T-shaped as at ,17,

40 the shank portions of said ends being flat- .tened at 18.: This' arrangement allows the hanger barsto have their T-shaped ends 1 17 slid the length r the slots 15, while re venting rotation offlthe bars with respect to thebricks, orvice versa. Y

, In building an arch-in accordance with my invention a number ofhanger bars 11- are suspended from each of the several frames A, the number of bars 11 depending'upon the;

numberiof bricks which are to comprise the ,arch; The- T -shape d end-17 of each of thehanger bars thenhas ,a brick'jl t disposed thereon. Upon proper shifting ofjhe hanger bars and the bricks, the'latter will be,

- arranged -so that their be in abutting-relation. A greater accu-. racy of adjustmentjis obviously obtained by 'having each. brick individually suspendedand amore neatly constructed and 'eflicient 7 arch is thus procured than would result from ordinaryand standard construction; When it be bars which I enadjacent faces will I v comes necessary to remove one; I of the bucks, orone' of the hangers, the Y proper hangerbar 11 is shifted longitudinally 6B of its supporting framegA-towardthe next adjacent hanger'bar, thus disposing its T- Y shaped end 17 in the'slot of the adjacent brick. as shown in Fig. 1. -The defective brick may then be lifted out of the arch or allowed to drop into the zfire box asdesired. operations of replacing a brick are of course then-eversebf those just setforth. 'After a brick is detached from its hanger bar, the latter may be removed from .itssupporting frame A by rotating it to 'a-line the head 12 with thean'gle bars 7 as prising. a support? including a longitudiwas hereinbefore I claim: H
